Our verdict
Our premium cooling pick. A 60mm graphene-infused iGel layer sits above a 4,000-spring dual-layer system and plush top, giving hot sleepers a very different option from dense memory foam or natural-fibre mattresses.
Best for
- Sleepers who overheat on foam mattresses
- Buyers who want a plush surface with responsive springs
- Shoppers who need a soft, medium or firm choice
- Buyers comparing cooling-led premium hybrids
Consider an alternative if
- You dislike gel or foam comfort layers
- Your bed frame or bedding cannot take a 34cm mattress
- You want natural fibres in the comfort build
- You are shopping below £1,500
Why we picked the iGel NanoTech 4000i Plushtop
Cooling here is a construction decision rather than a claim: the graphene-infused gel layer is substantial, and the dual-layer spring unit leaves internal space for airflow.
The 4,000 dual-layer springs combine mini and full-height springs, so the plushtop surface sits over responsive support rather than a single spring unit.

Is it good value for money?
The reference price shown is a list price before any qualifying order-level promotion, so the figure you pay may differ.
For hot sleepers who still want sprung support, the specification is strong for the money. Buyers who dislike gel or foam comfort layers should look at Hypnos or the Luxe-Latex natural build instead.
Who should buy the iGel NanoTech 4000i Plushtop?
Hot sleeper
Temperature is your main complaint, and you want cooling engineered into the mattress.
Plush-surface buyer
You want a cushioned top with springs beneath rather than a firm premium surface.
Firmness-choosing buyer
You want to pick soft, medium or firm rather than accept one fixed feel.
